Fazla Kilolu Olmak Çocuklarda Koroidi Nasıl Etkiler?

Öz

Amaç: Bu çalışma kilo fazlalığının çocuklarda koroid kalınlığı (KT) ve koroid vasküler indeksini (KVİ) üzerine etkisini karşılaştırmayı amaçlamıştır. Materyal ve Metot: Çalışmaya 44 fazla kilolu ve obez çocuk ile 35 normal kilolu çocuk dahil edildi. Katılımcıların tam oftalmolojik muayenesinin ardından optik koherens tomografi ile makula ve koroid görüntüleri alındı. Foveanın merkezi makula kalınlığı, subfoveal, 1000 µm nazal ve 1000 µm temporal KT ölçüldü. Toplam koroid alanı (TKA), luminal alanı (LA) ve stromal alan (SA), ikilileştirme yöntemi kullanılarak ölçüldü. Bulgular: Aşırı kilolu grubun ortalama vücut kitle indeksi (VKİ) değeri 27,70±1.55; obez grubun ortalama VKİ değeri 35,73±3,84; kontrol grubunun ortalama VKİ değeri ise 21,56±1,44 idi. Subfoveal KT, TKA ve SA değerleri gruplar arasında anlamlı farklılık gösterdi (sırasıyla p=0,019, p=0,016, p=0,028). BMI ile subfoveal KT, TKA ve SA arasında anlamlı pozitif bir korelasyon mevcuttu (sırasıyla r=0,264, p=0,019; r=0,233, p=0,038; r=0,231, p=0,041). Sonuç: Obez grubun subfoveal KT, TKA ve SA değerlerinin kontrol grubuna göre anlamlı derecede yüksek olduğunu gösterdi. Ayrıca VKİ ile subfoveal KT, TKA ve SA arasında anlamlı pozitif korelasyon bulundu.

How does being Overweight Affect the Choroid in Children?

Abstract

Objective: The study aimed to compare the effect of overweight on choroidal thickness (CT) and choroidal vascular index (CVI) in children. Materials and Methods: This study included forty-four overweight and obese children and 35 children with normal weight. After a complete ophthalmological examination of the participants, macula and choroidal images were taken with optical coherence tomography. The fovea’s central macular thickness, subfoveal, 1000-µm nasal, and 1000-µm temporal CT were measured. Total choroidal area (TCA), luminal area (LA), and stromal area (SA) were measured using the binarization method. Results: The mean body mass index (BMI) value of the overweight group was 27.70±1.55. The obese group was 35.73±3.84, and the control group was 21.56±1.44. Subfoveal CT, TCA, and SA values significantly differed between the groups (p=0.019, p=0.016, p=0.028, respectively). A significant positive correlation existed between BMI and subfoveal CT, TCA, and SA (r=0.264, p=0.019; r=0.233, p=0.038; r=0.231, p=0.041, respectively). Conclusions: The obese group had significantly higher subfoveal CT, TCA, and SA values than the control group, and a significant positive correlation was found between BMI and subfoveal CT, TCA, and SA.
